No, I can go a full week without using it. And I teach mathematics!
Everyday life is frequently irrational.
Here's an idea: Actually TRY to think before you start asking the answers to your homework questions on here...
Some numbers such as pi, e, and square roots are used quite commonly. Whether you use them at all will depend on what you do in your everyday life, of course. Engineers might use them commonly; others not so much.Even for an engineer, or ESPECIALLY for an engineer, the distinction between rational and irrational is irrelevant for most practical purposes; for instance, if you round pi, or the square root of 2 (which are both IRRATIONAL), to 10 or 15 significant digits, you get a RATIONAL number - and the resulting precision is more than enough for most purposes. (In fact, if you round to ANY number of digits, the result will still be rational.)

The German word "sorge" means "worry" or "concern" in English. It is commonly used in everyday language to express feelings of anxiety or unease about a situation or a person.
The square root of the number 31 is irrational. This is used in math.
"Irrational" is an adjective. It is used to describe something that is not based on reason or logic.
Irrational numbers are used in some scientific jobs. Commonly used irrational numbers are pi, e, and square roots of different numbers. Of course, if an actual numerical result has to be calculated, the irrational number is rounded to some rational (usually decimal) approximation.

Figures of speech can be used in both formal and informal English. They are often used to add depth and creativity to language, whether in professional writing or everyday conversation.
Irrational numbers can not be expressed as fractions whereas rational numbers can be expressed as fractions
